Enable multiple users to do something all at once by giving their group a
role.
A user group can have any number of roles. Each member of the user group has all
the access permissions allowed by all of the assigned roles, plus any permissions that
may have been assigned by other methods, such as application permissions or individually
assigned roles.
Note: When you give a group access to a CVS or Wandisco Subversion repository,
members of the group can view the repository but cannot do repository actions, such
as commit and update. You must assign those permissions to users
individually.
The roles are now assigned to each user group.
